The Wells Johnson Hercules Aspirator (#20-5007-00 / 110 V) is certified to proper operating specifications, and in like-new condition. Warranty: 90 Days Parts & Labor. The Hercules Aspirator features state-of-the-art technology in exterior component design with a new space-age polymer casing that's scratch resistant and defies denting. The Hercules, with 3 high-powered dual-cylinder piston pumps, is the most powerful aspirator on the market, and yet its operation is quiet to the ear. Standard all brass fittings resist corrosion, and pre-tested high pressure tubing exceeds all industry requirements ensuring reliability for years to come. The Hercules Aspirator is a high-powered suction system with 3 oil-less piston vacuum pumps. The system is designed to pull a vacuum on any closed container or any open process system. Vacuum is accomplished by mounting the vacuum pumps in parallel. When the aspirator is connected, the air flow will come from the tip of the cannula through the tubing, collection system, overflow trap, bacterial filter, and finally to the pumps evacuate the air from the lines, creating a vacuum pulling aspirated material in the same direction as the air flow. Aspirated material continues to the collection system under normal suction until the cannula is exposed to air again. Wells Johnson Hercules Aspirator Specifications: Weight: 73 lbs.
